# Part 1: What is expected from this series?

## 🔹 Introduction

*   Why CI/CD pipelines are critical for modern cloud deployments.
    
*   The importance of integrating **security checks, automation, and monitoring**.
    
*   A quick overview of the tools used: Jenkins, GitHub, OWASP, SonarQube, Trivy, Docker, Argo CD, Prometheus, and Grafana.
    

## 🔹 Architecture Overview

*   **Developer → GitHub → Jenkins CI/CD → AWS EKS**.
    
*   CI pipeline handles **code quality, security scans, and image builds**.
    
*   CD pipeline handles **deployment automation and monitoring**.
    
*   Monitoring stack (Prometheus + Grafana) ensures visibility.
    
*   Notifications via email keep stakeholders updated.
    

## 🔹 CI Pipeline Stages

1.  **Code Checkout** → Jenkins pulls code from GitHub.
    
2.  **Dependency Scanning (OWASP)** → Detects vulnerable libraries.
    
3.  **Code Quality (SonarQube)** → Enforces coding standards and quality gates.
    
4.  **Security Scan (Trivy)** → Scans filesystem and Docker images for vulnerabilities.
    
5.  **Docker Build & Push** → Builds container images and pushes to Docker Hub.
    
6.  **Version Update** → Updates Kubernetes manifests with new image tags.
    
7.  **Commit Back to GitHub** → Ensures GitOps workflow consistency.
    

## 🔹 CD Pipeline Stages

1.  **Trigger from CI** → Jenkins CD job starts.
    
2.  **Argo CD Deployment** → Syncs manifests from GitHub to AWS EKS.
    
3.  **Kubernetes Execution** → Deploys updated pods/services.
    
4.  **Monitoring**:
    
    *   **Prometheus** → Collects metrics.
        
    *   **Grafana** → Visualizes dashboards.
        
5.  **Notifications** → Email alerts on pipeline completion.
    

## 🔹 Tools & Integrations

*   **Jenkins** → CI/CD automation.
    
*   **GitHub** → Source control + GitOps repo.
    
*   **OWASP Dependency Check** → Security scanning.
    
*   **SonarQube** → Code quality analysis.
    
*   **Trivy** → Vulnerability scanning.
    
*   **Docker Hub** → Image registry.
    
*   **Argo CD** → GitOps deployment.
    
*   **AWS EKS** → Managed Kubernetes cluster.
    
*   **Prometheus & Grafana** → Monitoring and visualization.
    
*   **Email (SMTP)** → Notifications.
